Acompany produces metal slabs for industrial use. the slabs come in three thicknesses: 5in, 10in., 15 in. the weights of each thickness for each metal are given below. metal 1: 150lbs, 300lbs, 600lbs metal 2: 130lbs, 260lbs, 390lbs metal 3: 310lbs, 620lbs,930lbs metal 4: 140lbs, 280lbs, 420lbs for which of the metals weight not proportional to the thickness? a.) metal 1 b.) metal 3 c.) metal 4 d.) metal 2

5, 10 ,15  

divide each by 5

1,2, 3

so the ratios should be 1,2,3

Metal 1 : divide by 150

1,2,4

Metal 2 divide by 130

1,2,3

Metal 3  divide by 310

1,2,3

Metal 4 divide by 140

1,2,3

Metal 1 is not proportional

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
